Whilst browsing a geography site for some other info, I noticed an interesting blog entry (on the same site) about a long river cave on the island of Palawan in the Philippines:

The basic facts, of a 24km long cave system with an 8km river section, seem to be echoed in a Wikipedia entry:
https://en.wikipedia.org/wiki/Puerto_Princesa_Subterranean_River_National_Park
I wonder whether any Philippines specialists here can shed light on this cave? It doesn't appear in the world's long caves list at caverbob.com - maybe because the explorers never submitted details, or little is known about it? Of course the caverbob site could be out of date, too. Apparently.....
"In 2010, a group of environmentalists and geologists discovered that the underground river has a second floor, which means that there are small waterfalls inside the cave. They also found a cave dome measuring 300 m (980 ft) above the underground river..."
Somewhat vague but not uninteresting (and recent) details for a cave which should be in the world's top 200 longest caves. Anyone any ideas on the source of data for the cave length, or the exploratory group involved?
